16NiCrMo12 (UNI 7846)

 

PROPERTIES AND EMPLOYEMENTS
IT IS A CASE-HARDENING STEEL WITH PARTICULARLY ELEVATED MECHANICAL CHARACTERISTICS. THE REMARKABLE QUANTITY OF ALLOY ELEMENTS (ESPECIALLY Ni) CONFERS THE NUCLEUS AN ELEVATED HARDENABILITY AND RESISTANCE, COMBINED WITH AN EXCELLENT TOUGHNESS AND FATIGUE STRENGTH.
IT IS SUCCESSFULLY EMPLOYMENT IN SUBSTITUTION OF 16NiCr11 AND OF ALL THOSE CASE-HARDENING STEELS THAT HAVE A HIGH CONTENT OF NICKEL AND CHROMIUM THAT ARE NOT UNIFIED. IT IS ALSO USED FOR THE CONSTRUCTION OF PARTS THAT ARE SUBJECT OF REPEATED IMPACTS AND/OR STRONGLY STRESSED.
WITH NORM EN 10084, 16NiCrMo12 WAS SUBSTITUTED WITH 14NiCrMo13-4, WHICH HAS SIMILAR CHARACTERISTICS.

Steels

Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality. The constant quality of the supplies allows to have repetitive parameters in mechanical processing and a greater control over deformations during heat treatment.
